1 Claim.

'Ihe invention relates to an overhead 4door and more especially to an overhead door operating mechanism.

The primary object of the invention is the provision of a door of this character, wherein through mechanism the door will swing from vertical closing position to an overhead open position and when in vertical closing position will be latched while on the moving of the door to overhead position it will function as a canopy or awning to the doorway and will be entirely out of the way as to avoid obstruction of the space in and about the doorway.

Another object of thel invention is the provi sion of`a door of this character, wherein the same is of one piece and operates in a vertical direction for the travel thereof overhead when moved from closing position, the mechanism for operating the door being of novel construction and assures the easy working of the door to permit it to be closed or opened.

Another object oi' the invention is the provision oi a door of this character, ,wherein the saine when latched closed and its latch is released the door isinitially turned on its horizontal axis for the bringing of such door to a horizontal position overhead when traveling upwardly in a vertical direction.

A further object of the invention is the provision of a door of this character, which embodies simplicity of construction and economy of cost and also capable of being quickly and easily installed and is easy of operation and durable in use.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawings:

Figure/,1Q is a vertical transverse sectional view through a building, exampling a garage showing the door constructed in accordance with the invention applied and closed.

Figure 2 is a sectional view on Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 it a top plan view of one of the guide pulleys.

Figure 5 is an elevation partly in section of the Weight device employed for the door operating mechanism.

the line 2.-2 of Figure 6` is a view similar to Figure 3 showing the door in its raised overhead position, this positiony being shown by dotted lines in Figure 3.

Figure 7 is a fragmentary sectional view on the line 'I-1 of Figure 3.

Similar reference charactersA indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally the door proper and this door l0 may be of'any suitable dimensions and employed for closing a door opening or doorway to an edifice I0 which may be a garage, factory, -warehouse, barn or other `building, only a portion of the edifice being shown. The door opening or 15 doorway is constituted by a framing II providing vertical guideways I2. The framing is formed with vertical slots I3 aii'ording clearances for turning pivots I4, these being xed to the inner face of the door A in a horizontal plane common au to each other below the transverse center of said door. The pivots I4 extend laterally from the door A into the guideways I2 in which laterally travel half circular gockers I5 which are fixed tothe pivots I4. E gaged about the hub 25 portions of the rockers I5 re the loop terminals I6 of raising and lowering cables I1 which are trained ,over guide pulleys I8 xed to the heading I9 of the framing II for the door opening or doorway. The other loop ends 2li of the cables 30 I1 are engaged with a bail 2l for a weight 22, the latter being augmented by separable additional weights 23 removably fitting the bail 2|. The purpose of the weight 22 is to overbalance the door A when released from the door opening 35 or doorway in the framing II so as to automatically lii't the said door A to an overhead position. In this overhead position the door serves aas a canopy or awning to the door opening or doorway as such door projects inwardly and out- 40 wardly through the door opening or doorway overhead. l

Next to the top edge of the door A preferably at the longitudinal center thereof is a spring tensioned latching bolt 24 which engages the 45 keeper 25 on the framing II when the door is in vertical closingposition so that said door/may be latched. 'Ihis bolt 24 has connected'thereto an operating chain L26 which extends/'to a crank 21 for the manual releasing of ther bolt 24. At 50 the lowermost portionsof the door preferably on the outside thereof is a loop handle 28. .The hand crank 21 is operable from either the outside or inside of the door A.

Adjacent to one side edge of the door is a pull 55 'that a tension is h chain 26 which depends from the door when in overhead position and is properly located sothat it may be conveniently reached by an operator and on pulling upon such chain the said door can be shifted from overhead position to a lowered vertical position for the closing of the door opening or doorway.

When the door A is in lower vertical position it ts withinthe door opening or doorway and the bolt latches the same in closed position.- When the latch is released the door is free to move upwardly and overhead. In this overhead position the door functions as a canopy'or awning for the door opening or doorway.

The rockers at the circular edges thereof, each is formed with a'. laterally extending iiange 30, it having a mutilation forming a passage or notch 3l for the cable l1. Now when the door is in closing position it \wi11 be noted that the ange 30 next to the notch^3| canters the cable I1 so by instantly on the unlatching of the door A this 25 vertically. Then when the door is in `m11 open upon the rocker I5 whereposition the ange 30 acts upon the cable I 'l to slightly distort the same reversely to the cantor of such cable |11 when thedoor is in open podtion, 'this being clearly shown in Figure 6 o! the drawings.

What is claimed! is: y

In a door of the character described, a wall having adoorway, framing for said doorway and forming vertical guideways, a door iitting salddoorway and having pivots arranged below the transverse center of said door, rockers traveling in' said guideway and xed to the pivots weighted cables connected with said rockers and automatically raising the door when released trom the doorway to overhead substantially horizontal position, means latching th'e door in the doorway and in a .vertical position, separable weights carried by the 'cableaguide pulleys above the doorway land having the weighted cables trained thereover, and means cooperating' with the rockers to Aeffect the tensioning of the cables when the door is in closing position for the initial swinsing of the door automatically when unflatched l p f o.
